Hey guys any help appreciated.

So i drive my quad at least 2-3 times a month. Earlier this month i tried starting it , usually it will start as soon as i turn the key but it took a bit for it to start after giving a bit of gas. the following week it wouldn’t start at all. kept turning over, so i got the spark plug and the ignition coil changed but it still wont start. it does turn over. gas is new. Need help!!

Also any help on where the fuel filter is located?
